Four workers were exposed internally while they were replacing a filter element of the vacuum filter installed in the sampling system connected to the plutonium receiving vessel of the rework process of the Tokai Reprocessing Plant on December 27, 1993. At the time of incident, operation of the Tokai Reprocessing Plant was stopped for routine maintenance from December 5, 1993. The cause of the internal exposure was that the four workers inhaled plutonium particles dispersed from the filter element in the vacuum distribution room. The floor of vacuum distribution room was contaminated by this radioactive release. The bio-assay analysis results on January 11, 1994, showed that the maximum estimated internal exposure over 50 years was 90 mSv of effective dose equivalent and 1700 mSv of tissue dose equivalent for one of the 4 workers. Both dose equivalents exceeded the legal dose limit (50 mSv/y and 500 mSv/y), respectively. The rating of this event is classified at level 2 under the on-site impact criterion.

Everywhere you look, the nuclear industry’s hype machine is in overdrive. Goldman Sachs, Microsoft, and the UK government all tout small modular reactors as the silver bullet for climate change and energy security. Tech billionaires are hiring nuclear veterans. Wall Street is whispering about “round-the-clock power” for artificial intelligence data centers. For those old enough […]
Kernenergie en veiligheid: A wargame sought to test if a major radiological release that would prompt the evacuation of millions of civilians in South Korea could distract key US allies from assisting and rebuffing an all-out military invasion of Taiwan. The short answer was yes. The game originally presumed that China, wanting to keep the […]
Big batteries and EVs to the rescue again as faults with new nuclear plant cause chaos on Nordic grids The Finnish nuclear power plant Olkiluoto was finally connected to the grid last year, at an estimated cost of €11 billion compared to the original budget of €3 billion. That cost blowout forced its developer, the […]
